振動監視装置。[Claim for Utility Model Registration] In a device that compares the output of a sensor provided in a reactor with an alarm level and outputs an alarm if the output exceeds this level, the output of the sensor is compared with the activation level that passes through during activation. A comparator that operates for a certain period of time from when that level passes, a timer that operates for a certain period of time from when the level passes, a comparator that compares the output of the sensor with the stop level that passes when stopping, a timer that operates for a certain period of time from when that level passes, and when the above activation occurs. A reactor vibration monitoring device comprising: a control circuit that does not output an alarm signal according to the alarm level during the operating time of the timer and the stop timer, respectively.
